This invention relates to certain new and useful improvements in smoking pipes and it particularly has for its object to provide a V reference llldlcflte'llke parts in all of the figeures, 1 1 represents the bowl which has the i pipe with a simple and effective means for -5 condensing and trapping saliva so that only the dry smoke will pass through the mouth piece. g

Further, the invention has for an Ob](3t to provide a smoking pipe characterlzed as above which, to all outward appearances, does not differ from the ordinary pipe inwhich the bowl and stem are integral and the mouth piece is separable from the stem.

Fupther, the invention has for its object 1 to provide means whereby the condensed and trapped saliva is collected in a removablereceptacle located in the stem and in which the parts are so coordinated and cooperatively arranged that accumulations of saliva in the -2 chamber of the stem around, the collection receptacle or between it and the bowl end of the stems chamber are avoided.

Further, it is an object to provide a smoking pipe characterized as above in which the saliva collection receptacle is designed to cool the smoke as it passes through, thereby delivering the smoke dry and with the full flavor of the tobacco used.

A further object of the invention is to 3 provide means whereby the pipe may easily be cleaned and to so construct the saliva collection receptacle that it can be withdrawn from the pipe stem even though it fit the stem in a manner causing more or less retaining 3 friction.

Other objectswill in part be obvious and in part be pointed out hereinafter.

To the attainment of the aforesaid objects and ends, the invention still further resides in the novel details of construction, combination and arrangement of parts, all of which will be first fully described in the following detailed description, then be particularly pointed out in the appended claim, reference being had to the accompanying drawing, in which Figure 1 is a side elevation of my improved pipe.

Figure 2 is an enlarged vertical longitudi- V 9 nal section of portion thereof.

Figure 3 is across section on the line 3-3 of Figure 2. p

In the drawing in which like numerals of usual tobacco chamber 2 and theusual stem 3, thelatter inthis case being provided with a cylindrical bore. or chamber 4 entering from the outer end of the stem, 7

15 Is themouth piece which is provided with no the usual stopper 6 to fit into the outer end of the stem 3 in a manner to befrictionally retained ortthe two partsmay be screwed together if desired, this construction being common practice. Themouth piece 5 has the usual smokeduct 7 and in this-case it is counterbored at 8 to receive a short tube 9 which prcjectsbeyond the end of the stopper 6 into the tubular receptacle 11. o I

I The-tubular receptacle 11 isclosed atone :0 end by a permanent wall 12 and is of such a lengththat when the parts are assembled (see Figure 2) the wall-12will lie against the bot tom wall 13 of the chamber 4, while. the open end of the receptacle 11 will abut and be closed 7.

by the stopper 6.

/ The receptacle 11 has a shallow longitudinal groove 14 extendingfrom end to end at its highest level and the gTOOVQtll registers with a port 10 of approximately the same area as the cross section-of the groove, for effecting communication between the smoke chamber 2 and the groove 14, a

Adjacent the stopper 6 the receptacle 11 is apertured at 15 vto; provide aport for passing thesmoke from thehigher end of the groove 14 into'the interior of the receptacle 11, the short tube 9 projecting into the receptacle beyond the place where the-port 15 is located so as to cause a-reverse flow of the smoke and trap the condensate in'the receptacle 11,

which condensate gravitates toward the low est point of the receptacle. It is to be noted that the preferable construction of my pipe requires that the receptacle 11 be of substantially thelength of the chamber 4 between the wall 13 and the end of the stopper 6 so that there will be no space between the walls 12 and 13 in which matter may accumulate, thus luv The location of the hole-'15 adjacent the outer end of the receptacle l1 enables a hook to be inserted after the mouth piece has been taken off and the receptacle pulled out, it of course being understood that the receptacle is preferably held in place by retaining friction with the groove 1a in register with the port or passage 10.

While I prefer to locate the opening 15 a slight distance from the end of the receptacle 11 in order that it may take a hook for puling the receptacle out, it may be located at the extreme edge if desired, as the exact location of the opening 15 with relation to the extreme end of the receptacle 11 is not essential. This location may-be shifted as may be found desirable. It should, however, be located in such a position as to be between the exposed end of the tube 9 and the end of the stopper 6 in order that the reverse flow of the smoke may be had. 7 4 Y I am aware that attempts have been made to provide pipes with devices for trapping WILLIAM GEORGE CLARK.

the saliva but such pipes as have come to my attention, a're-tooexpensive and complicated in their construction and arrangement, and furthermore such pipes, by virtue of their peculiar constructions, leave pockets in the bowl or stem portion of the bowl in which saliva and other matter can accumulate and in time clog the action of the pipe, making it necessary to scrape'the stem'and bowl in order to clean it after having taken the pipe apart,

whereas in my construction no scraping of the stem is ever required. Should it'be found that any material has accumulated on the wall of the stem'which is in alignment with the groove of the receptacle, all that is neces sary is to give the receptacle a turn about its axis when it will cut any material automatically.

' Other objects and advantages of my invention will be clear to those skilled in the art to which it relates.

What I claim is: 5 In pipes, a bowl having a tobacco chamber anda' stem projecting fromthe bowl as an integral structure, said stem being provided with'a boreentering from its outer end and terminating short of the tobacco chamber of the end wall of said bore and having its other end located adjacent said stopper portion, said receptacle having an inwardly directed longitudinal groove along its outer surface extending from end to end, said bowl having a smoke'port lcadingfrom said tobacco chamber at a substantial distance from the bottom thereof to the adjacent end of said longitudinal groove, said receptacle at its end adjallt
